The new config format is based on the new network configuration subsystem.
Includes a few config fixes to NetworkConfigLoader and InterfaceManager.

* Added PartialFailureContraint to MP2SP intent to allow partial connectivity.
This means the intent remains installed as long as at least one ingress point
can reach the egress point.
* Intents with this constraint are recompiled on ObjectiveTracker triggers
even if not in FAILED state
* MP2SP intent compiler can compute a partial tree if constraint is set
* ObjectiveTracker recompiles intents on any link event
* SDN-IP MP2SP intents now use PartialFailureConstraint
Ported from onos-1.2 branch.

There is no physical gateway in SDN network.
However a host needs a gateway when it tries to communicate with a remote host.
So we designed a virtual gateway for SDN network.
The virtual gateway can have multiple IP addresses.
Each IP address is used as the default gateway address of an IP prefix.
We only configure one MAC address to the virtual gateway.
You can choose any MAC address from the BGP speakers as the virtual gateway MAC address.
We configure this MAC address staticly in the sdnip.json configuration file.

This module can handle 3 cases:
(1) one host wants to talk to another host, both two hosts are in SDN network.
(2) one host in SDN network wants to talk to another host in Internet.
(3) one host from Internet wants to talk to another host in SDN network.
In all cases, we use MultiPointToSinglePointIntent.

- Each connectivity intent now has only one constructor
- Intent constructors are now private for leaf classes and
protected for classes that can be derived from
- Each intent class has a Builder class that accumulates
parameters for intent creation
- Each intent class has a public static builder() method
to create a builder
- Each Builder class has a build() method to create the
intent from the accumulated parameters
- Added keys to a few intent types that were missing them
- Tightened up usage of checkNotNull(), taking advantage of
the return value to save some lines of code
- Modified callers to use the builders instead of directly
calling the constructors

* Use intent priority when installing multipoint-to-singlepoint intents:
the loinger the routing prefix match, the higher the intent priority.
This is needed to perform correctly the equivalent of longest prefix
match in the switch.
* Use intent priority for the point-to-point intents: the priority for
this BGP-related control traffic is higher than the
multipoint-to-singlepoint intents.
* Use the appropriate Key when installing multipoint-to-singlepoint intents.
The key is the network (destination routing) prefix address represented
as a string.

Note: There was a change that adds a DROP action to
a traffic treatment if there are no other actions present.
To get a traffic treatment without the drop rule, use
emptyTreatment()

This allows the configuration to be used from multiple applications.
* The class that reads the configuration file is now a service so that
config can be consumed by components in other bundles.
* Name of config reader classes has been generalized to RoutingConfigService
* All config has been added to RoutingConfigService, instead of having
two service interfaces like we did previously

The main goal of this is to allow routing code to be used by multiple
applications.
Changes include:
* Created an onos-app-routing bundle and moved BGP code and routing code
into it.
* Created an onos-app-routing-api bundle as a common API bundle between
onos-app-routing and onos-app-sdnip, to prevent circular dependencies.
* Moved API classes into onos-app-routing-api bundle.
* Made Router and BgpSessionManager into OSGi components. This is not quite
clean, because there is still a chain of start() method calls from SdnIp
through to BgpSessionManager to preserve startup order. This should be
revisted so components can be started using activate()
* Created BgpService and RoutingService APIs to glue different components
together.
* Many unit test changes. A lot of the previous unit tests spanned the
Router and IntentSynchronizer classes, but this is not possible any more
since these classes are in different bundles. I had to rewrite some of
these tests so that each unit test class only tests one real class. A
nice side-effect is that the tests are now simpler because each test
tests less functionality.
* Removed SdnIp test seeing as it doesn't run automatically, was already
broken and has been largely superseded by other unit tests and the nightly
functional tests.

* IntentSynchronizer implements a more generalized FibListener interface
* Updates to the FIB are signalled with FibUpdate to any FibListeners
* generateRouteIntent logic has been pushed down into the IntentSynchronizer

Previously, when checking the winning BGP routes, we expect-and-wait until
the size of the table with the winning routes has certain size, and
then we verify whether it contains a particular value.
This is error-prone and time-sensitive. For example, if we are testing
whether a particular route from one BGP peer is replaced with the
same route from another BGP peer, the test might fail because the
table size doesn't change.
Modified the unit test to expect-and-wait until the expected route
is received.
Also, fixed some of the paragraph tags in some of the Javadocs.

* Fix a bug in the storing, handling and verification of the AS numbers
with 4 octet AS capability is used.
* Add an unit test to test the decoding and parsing of supported
BGP Capabilities: Multiprotocol Extensions AFI/SAFI, and 4 octet AS.
* Minor refactoring of the BGP unit test framework.

Moved the local and remote BGP session info to a separate class BgpSessionInfo.
No functional changes.
Also, removed methods TestBgpPeerChannelHandler.prepareBgpKeepalive(),
prepareBgpNotification() and prepareBgpMessage() from the unit tests.
Instead, use the corresponding methods in the BGP implementation itself
to generate the BGP messages.

SDN-IP can now support peering and routing between hosts that are connected
on VLANs.
Changes include:
* Updated NetworkConfigReader app to read (optional) VLAN configuration
* Updated VlanId to support the 'VLAN present' value - in a match this means
that a VLAN tag must be present, but it can contain any value.
* Updated SDN-IP to set destination VLAN tag values if appropriate
* Updated FlowModBuilder and FlowEntryBuilder to support 'VLAN present' value
* Slew of test updates.

* The routing entries as received from BGP can be either IPv4 or IPv6
* The CLI prints the IPv4 and IPv6 routes
* The BGP peering is still over IPv4, so configuration-wise the IPv6
routes from the eBGP peers have to be configured to use the IPv4 peering.
* The integration/testing with the IPv6 Network Discovery Protocol is not
done yet.
* The integration/testing with IPv6 intents is not done yet.
Also:
* Moved nested class BgpSessionManager.BgpRouteSelector out of the
BgpSessionManager class.
* Code cleanup.

BGP OPEN Multiprotocol Extensions Capabilities (RFC 4760).
The corresponding BGP UPDATE decoding is not done yet, hence for now
we don't include any Capabilities in the BGP OPEN message originated by us.

* Resolves ONOS-476
* Moved the BGP message-specific processing from class BgpSession
to per-message type classes: BgpKeepalive, BgpNotification,
BgpOpen, BgpUpdate
* Minor modifications in some of the methods or BGP-specific API
to accomodate the above change.
No functional changes.
